Objective: To Analyze the association between prevalence of fatigue referred by physical therapists and their occupational exposure to radiation emitted by therapeutic microwave diathermy equipment. Methods: A Cross-sectional study conducted in 193 physical therapists from four cities of the west of Paraná State, Brazil. A specified structured web questionnaire was applied for collecting data about microwave diathermy exposition and potential confounders, plus the Multidimensional Assessment of Fatigue (MAF). Statistical analysis included logistic regression and Student's t-test. Results: The prevalence of fatigue in the category exposed to microwave diathermy was higher (15.0%) than in non-exposed (2.9%). On multivariate logistic regression, a significant independent association between exposure to microwave diathermy and prevalence of fatigue was observed (odds ratio 4.93; 95% confidence interval 1.04 - 23.25; p = 0.04). The Student's t-test showed significant difference between the number of hours exposed to diathermy microwave, being 3,839.1 within physical therapists who referred fatigue and 497.6 within others (p = 0.004). Conclusion: The results demonstrate a significant and independent association between occupational exposure of physical therapists to radiation of microwave diathermy and prevalence of fatigue. Therefore, occupational safety guidelines aimed at these professionals as a prevention of possible adverse effects, as well as the replication of this study are suggested.

Introduction: Chronic Kidney Disease (CKD) has become a major health issue worldwide. CKD patients require Renal Replacement Therapy (RRT) throughout their life. Haemodialysis is one of the options for RRT. Arterio-Venous Fistula (AVF) creation is required for haemodialysis. The radiocephalic fistula is the initial option for creating vascular access. Fistula can be created by anastomosing cephalic vein to radial artery either by End-To-Side (ETS) or Side-To-Side (STS) techniques. Aim: To compare the efficacy rate of radiocephalic AVF using ETS or STS anastomotic methods. Materials and Methods: This was a retrospective analytical study conducted at SDM college of medical sciences and hospital, Dharwad from March 2017 to February 2020. A total of 43 CKD patients were enlisted for the above duration from the hospital records. These patients were included in the study since they underwent radiocephalic AVF creation. AVF creation at other anatomical sites for rest of the CKD patients was excluded. Out of 43 patients, 24 of them underwent ETS technique and 19 STS technique; 15 patients from the former group and 17 from the latter were followed-up for a period of three months. Eleven patients were lost to follow-up. Demographic variables were analysed with frequency, mean and standard deviation. Its association with two different operative techniques was analysed using Fisher’s-exact test. Outcome of the two operative procedures was analysed using Student’s t-test. Results: Effectively 15 patients from ETS group and 17 from STS group were compared. Three (20%) in ETS group and 5 (29.41%) in STS group had primary failure. Mean of maturation time in weeks in ETS group was 4.73±2.73 weeks and in STS group was 5.29±3.75 weeks. Three months patency rate in ETS group was 12 (80%) and in STS group was 12 (70.58%). Student’s t-test was performed comparing the above parameters and no statistical significance was noted. Conclusion: Comparison of two techniques of radiocephalic AVF creation proves that both the techniques are beneficial with no superiority of one over other.

ABSTRACT Objective To investigate potential intravenous drug incompatibilities and related risk factors in a pediatric unit. Methods A cross-sectional analytical study conducted in the pediatric unit of a university hospital in Brazil. Data on prescriptions given to children aged 0-15 years from June to October 2014 were collected. Prescriptions that did not include intravenous drugs and prescriptions with incomplete dosage regimen or written in poor handwriting were excluded. Associations between variables and the risk of potential incompatibility were investigated using the Student’s t test and ANOVA; the level of significance was set at 5% (p<0.05). Relative risks were calculated for each drug involved in potential incompatibility with 95% confidence interval. Results A total of 222 children participated in the study; 132 (59.5%) children were male and 118 (53.2%) were aged between 0 and 2 years. The mean length of stay was 7.7±2.3 days. Dipyrone, penicillin G and ceftriaxona were the most commonly prescribed drugs. At least one potential incompatibility was detected in about 85% of children (1.2 incompatibility/patient ratio). Most incompatibilities detected fell into the non-tested (93.4%), precipitation (5.5%), turbidity (0.7%) or chemical decomposition (0.4%) categories. The number of drugs and prescription of diazepam, phenytoin, phenobarbital or metronidazole were risk factors for potential incompatibility. Conclusion Most pediatric prescriptions involved potential incompatibilities, with higher prevalence of non-tested incompatibilities. The number of drugs and prescription of diazepam, phenobarbital, phenytoin or metronidazole were risk factors for potential incompatibilities.

This study aims to explore the association between nurses' leadership styles and personal and professional nursing profile and workload. The sample consisted of seven nurses and seven nursing technicians who were grouped into pairs. At the end of three months, nurses were queried regarding what leadership style would be adopted when the nursing technician under their evaluation delivered care to patients admitted to the ICU. Relevant data was analyzed by applying descriptive statistics, Tukey's multiple comparison test and Student's t-test (p< 0.05). Nursing workload reached 80.1% on average. The personal and professional profile variables did not show any relation with the leadership styles chosen by nurses (p>0.05). The determine, persuade, and share leadership styles prevailed. However, whenever the nursing workload peaked, the determine and persuade styles were used (p<0.05).

Intravesical prostaglandin E2 is effective in the recovery of spontaneous voiding after transvaginal reconstruction of the pubocervical fascia and short arm sling according to Lahodny. The aim of the study was to compare the effects of intravesical prostaglandin E2 in the prevention of urinary retention after transvaginal reconstruction of the pubocervical fascia and short arm sling according to Lahodny. STUDY DESIGN: From November 1996 to June 1999 fifty women underwent the Lahodny procedure for moderate/severe cystocele and stress urinary incontinence. Women were randomly assigned to 1 of the 2 study groups: intravesical prostaglandin E2 versus controls. Data obtained were analyzed with the Student t test and the Fisher exact test. RESULTS: Two patients of the treatment group had to be excluded from the study, one because of the wrong measurement of the post-voidal residual volume and another due to a fastidious burning sensation which appeared immediately after prostaglandin instillation and required the suspension of the treatment. No other side effects such as nausea, vomiting, diarrhea or hyperthermia were observed. Patients who underwent the prostaglandin E2 treatment showed a recovery of spontaneous voiding after 7.9&plusmn;6.7 days, whereas this interval was significantly longer in the control group, being 12.9&plusmn;9.7 days (p=0.04, Two tailed Unpaired Student's T test). CONCLUSION: The effectiveness and the low associated morbidity mark the treatment with intravesical prostaglandin E2 useful in the recovery of normal voiding after transvaginal pubocervical fascia reconstruction and short arm sling with the procedure according to Lahodny.

Aim: To investigate the percentage of correctness (PC) of the Nasal Index (NI) in human skeletons for determination of sex, ancestry and estimation of age in the Brazilian population. Methods: This was a cross-sectional study of 173 human skulls belonging to the Piracicaba Dental School. 93 skeletons were males and 80 females; 34 were aged up to 39 years, 56 between 40 and 59 years, and 83 60 years or older; 96 were from white individuals, 49 were from mixed-race and 28 from black individuals. High-precision digital caliper was used to measure nasal height (NH=ANS-nasion) and the maximum nasal width (NW) values, which were applied into the formula NI=NW/NHx100. The data were submitted to discriminant analysis and Student’s t test with equal variances, Mann-Whitney, F (ANOVA), Tukey and Kruskal Wallis, 5% significance level. Results: Dominant nasal type in the Brazilian population was the mesorine. Males showed nasal height and width values greater than those of females, with statistically significant differences in all measurements (p≤0.021) and PC of 76.6%. Similar nasal measurements were found regardless of age (p>0.05), with PC of 41.7%. Ancestral analysis revealed that black individuals have greater nasal width (26.35) and nasal index (53.67) than white ones (24.60 and 49.25), while mixed-race individuals showed intermediate values (25.36 and 52.13) (p<0.05). Nevertheless, these measurements presented an estimated PC of 54.3%. Conclusion: The Nasal Index can be better used for sex determination than for estimation of age and ancestry in the Brazilian population, as the latter showed intermediate and low percentage of correctness, respectively.

Functional and structural damages of tubulointerstitium are caused by proteinuria. The aim of this study was to assess the influence of different proteinuria levels on Na+, K+, Cl tubular transport. We examined 50 patients (24 males, 26 females), mean age 46.50 ? 13.08 years, with mean creati-nine clearence of 87.29 ? 31.17 mL/min. They were separated in three groups depending on proteinuria value. The first group with proteinuria less than 0.3 g/24h included 19 persons (7 males, 12 females), mean age 45.12 ? 13.28 years, with mean creatinine clearance of 94.27 ? 34.70 mL/min. The second group of 18 patients (8 males, 10 females), mean age 45.39 ? 12.64 years had proteinuria of 0.3-3,0 g/24h and mean creatinine clearance of 90.07 ? 31.89 mL/min. The third group had proteinuria level higher than 3.0g/24h and mean creatinine clearance of 73.25 ? 20.44 mL/min. It included 13 patients (9 males, 4 females), mean age 50.08 ? 13.73 years. As a parameter of proteinuria influence on tubular transport of Na+, K+ and Cl-, fractional excretion of these electrolytes, was studied. Student's T test, Mann Whitney U test and c2 test were used for statistical analysis. No statistically significant influence of proteinuria was found on Na+, K+ and Cl tubular transport.
